Specification of Letters Patent.

Patented Dec. 21, 1920.

Application filed January 17, 1918. Serial No. 212,205.

To all '10]? omz, may concern Be it known that I, NiLs AnvIDssoN, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented a certain new, useful, and Improved Type-Bar-Casting Machine, of which the following is a specification.

lviy im'ention relates to the type casting art and has particular reference toimprovements in machines for casting or producing type bars or slugs. j

The object of my invention is to provide means whereby slugs, similar to so-called linotype slugs, can be readily, easily and quickly produced from a suitable line of matrices; to provide a machine which when once put into operation will operate automatically toproduce a finished slug; and to provide what may be termed a semi-automatic machine to produce skeleton slugs having various widths of faces.

A further object of my invention is to provide an adjustable core for use in producing skeleton type slugs in combination with means whereby the core is adjusted or sized in accordance with the thickness of the slug being produced. i

A further object of my invention is to provide a machine of the character described provided with anadjustable slug core and adapted for automatically producing both cored and uncored slugs, depending upon the thickness of the slug.

My invention consists in a slug casting machine having an adjustable slug core and means whereby the core is automatically adjusted in relation to the slug being castto properly core same.

My invention also consists in a machine of the character described having a slug core and means whereby the core is automatically positioned out of or within the slug casting space in accordance with the thickness of the slug. l

My invention also consists in the several combinations of devices, mechanisms and parts, and in the features of construction whereby i am enabled to attain the above mentioned and other objects and all as hereinafter described and particularly pointed out in the appended claims.

Machines for the production of type bars or linotype slugs, so far as I am informed, have been developed along two main lines, one the well known linotype machine and the other the Ludlow slug caster.

In the linotype machine, matrices circulate through the machine from a magazine in which they are stored to and through the casting mechanism and are then automatically distributed ready for use. In the Ludlow machine, on the other hand, the matrices are set up by hand and then resented to the casting mechanism. he matrices are re-distributed by hand.

My machine? more nearly allied with the latter type 0 machine in that I do not automatically handle the matrices, but I do provide a machine which when the matrix holder, carrying the necessary matrices thereon, is presented to the machine the machine automatically performs all of the necessary operations to deliver a finished slug.

In other words, by means of my machine Iam enabled to perform the following operations:

I present to the machine a matrix holder with the selected matrices properly clamped therein. I then, by means of a convenientlever, start the machine into operation and it operates automatically to perform the operations or functions. The holder is moved into position where the parts of the mold can properly close to form a, mold suitable for the slug which is to be cast. The mold then closes and the metal pot is advanced into proper contact with the rear face of the mold parts. Just before the contacting of the mouth of the metal pot with the mold an adjustable core is positioned in the slug space, if the slug is more than a certain thickness, which core is automatically adjusted to core as much as possi ble out of the slug in order to make the slug of a minimum weight and use up a minimum quantity of metal. Should the slug be thinner than the said certain thickness, the core is automatically shifted out of casting position and the slug is cast solid.

After the mouth of the metal pot is contacted with the mold, the casting mechanism operates to force hot liquid metal from the pot into the mold. The pot is immediately withdrawn and while the slug is held between the parts of the mold a knife operates to trim the bottom of the slug. Then the mold opens, the matrix holder is forced rearwardly and is turned in such a manner that the cast slug hangs down. The machine continues to operate and automatically draws the cast slug out of the holder and deposits it in the receiving compartment.

Having accomplished this function, the machine comes to a stop ready to go through the operation again, once it is started or released.

As shown in said drawings, I provide a suitable frame which carries the various parts of the machine. Upon the front part of the machine I provide a table 2 which is movable up and down to adjust the machine for varlous thicknesses of slugs.

Upon the middle part of the frame I mount a metal pot 3, which may be heated by any suitable means not shown, and which holds the molten metal with which to make the slugs.

The pot is mounted on a cross shaft or rod 4: so that it can be tipped or swung forward to make a cast and back to clear the mold and trimming knife.

Between the metal pot and table 2, I'provide rigid side uprights 5, their upper ends rigidly connected by a cross bar 6 to form a frame within which the upper and lower members of the mold are held. The lower part 7 of the mold is rigid and stationary, and the upper part or cap 8 of the mold is movable up and down between the uprights 5.

Upon the table 2 I mount a transversely can ling bar 9 which is movable toward and away from the mold and is guided by means of dove-tail projections 10 which it within similar shaped openings or slots in the upper face of the table 2; the bar 9 is movable away from the mold a SUiilClGllt dis tance to pe mit the positioning of the matrix iolder ll on the table and between the bar and the mold and in such position that when the bar is moved toward the mold the matrix holder will be forced toward the mold for properly positioning the matrices in. relation to the mold for casting a slug. The matrix holder 11 consists of a lower longitudinal bar 12, an upper bar 13, and spacers la and 15, thus providing a rectangular frame within which the matrices can be arranged and by which they can be held. Within the end spacer or member 14. I arrange a removable block 16 and at the opposite end ofthe line of matrices I provide a similar block 17. Each of these locks is provided with a rearwardly e1: tending projection 18 whose height vertically relatively to the matrices is coincident with the thickness of the slug to be cast. In Fig. .18 these projections are relatively high as the slug to be cast by means of these matrices I is relatively thick. Such slug being clearly shown in Fig. 25. In Fig. 15 these projections are relatively thin vertically and are adapted for the production of a thin solid slug as is illustrated in Fig. The end member 17 is movable longitudinally of the matrix holder so that it can be forced inwardly against the line of matrices 19 which are being held in the matrix holder and is adapted to be held in its matrix clamping position by means of the bolt 17. The projections 18 of the blocks 18 and 17 are provided on their rear ends with V-shaped notches or openings 20 whose functions will be developed hereinafter. The inner face of the matrix holder is provided with upper and lower bars or plates 12 and 13, respectively, which overlap the matrix space within the holder and in combination with the bar 9 hold the matrices rigidly against movement forward and back. The projections 18 are adapted to close the ends of the portion of the mold slot being used, and the upper and lower parts of the mold are provided with plates 22:3 and 24-, respectively, which project into the matrix holder so that their front edges will properly contact with the inner edges of the imitrices and seal the joint between the mold and matrices to prevent the escape of the molten metal at these points.

It is quite common to use what are known as two letter matrices which have two character forming recesses, one above the other, and for the purpose of being able to arrange the matrices in a line so that the proper character recesses will be presented in alinemeat to form the slug, I provide a removable horizcontal bar or filler 22 adapted to rest upon the upper edge of the lower plate 12 and raise the matrices which rest thereon sufliciently to bring the lower character recess in alinement with the upper character recesses of those matrices which rest upon the lower bar 12 of the holder, as shown in dotted lines in Fig. 19.

When the machine is in position to receive the matrix holder the bar 9 is at the rear limit of its movement and is held locked in such position by means of latch springs 21 mounted upon the table 2 and adapted to engage the lower edge of the bar 9 to hold it against forward movement.

To more the bar 9 and the matrix holder forward. when it is desired to cast a slug, 1 provide springs 25 having their inner ends mounted upon the side bars 5 and their outer ends upon the bar 9 and tending to draw liar 9 toward the mold. Upon releasing of the bar 9, by the depression of the latch springs 21, by means of mechanism to be described, the springs 25 operate to draw the bar 9-and matrix holder into the position shown in Fig. 4:, wherein the projections 18 are positioned between the upper and lower parts of the mold and the plates 23 and 2a are positioned with their forward edges in proper contact with the inner faces of the matrices.

For providing means for the various mechanical movements of the several parts of the machine, I provide a horizontal transverse shaft 26 mounted for rotation upon the rear part of the machine and pro vided with the necessary cams for operating the various parts of the machine and designed to move the several parts at their several related periods.

As the bar 9 with the matrix holder is moved forward into position within the mold, the mold cap 8 is moved down into tontact with the projections 18 by means of levers 27 which are pivoted one upon each side of the machine, their forward ends be ing operatively connected to the opposite ends of the mold cap 8 and their rear ends provided with anti-friction rollers 28 which engage suitable cams 29 rigidly mounted upon the shaft 26. The forward end of each of these levers is provided with a horizontally extending pin 29 which is movable in a slot 30 in the mold cap 8, and when it is depressed it engages a spring 31 and pushes the mold cap down.

its explained hereinbefore, the projections 18 are of different thicknesses vertically, de pending upon the thickness of the slug to be cast. The lower faces of these projections. when they are within the mold, rest upon the lower mold plate 7, and as these projections are arranged centrally of the matrix, opposite to or in line with the character forming recesses in the matrix, the lower surface of these projections vary in height from the lower surface of the matrix holder and consequently the table 2 must be raised or lowered in accordance with the thiclmess of the slug being cast so that when the ma trix holder is arranged with the projections 18 within the mold, the lower faces of these projections will properly contact with the lower plate 7 It will be clear that the mold cap 8 must necessarily move down from its upper po sition a distance suthcient to contact with the projections 18. this distance to be moved depending upon the thickness of the projections 18, as the projections must be tightly clamped, whenever a slug is cast. between the upper and lower parts of the mold. This varying movement of the mold cap is provided for by means of the slot and pin con nection with the springs 81 between the levers 2-7 and the mold cap.

For moving or adjusting the table 2 up and down I provide a simple arrangement of vertical screw threaded shafts 32 below neath the table top, each carrying a miter wheel and their upper threaded ends 34 engaging threaded brackets 35 secured to the outer part of the table top. These shafts are mounted in suitable bearings 36 secured to the frame which hold the shaft against vertical movement. I provide also a horizontal shaft 37 near the front of the table mounted in suitable bearings and carrying a hand wheel having on its face suitable indicating marks 39, and at its ends having miter wheels 40 adapted to engage the miter .vheels upon the forward shafts 32. I also provide horizontal shafts 4i mounted in suitable bearings and carrying at its ends miter wheels 42 adapted to engage the miter wheels 33 on both forward and rear shafts $32, one of these shafts all being arranged at each end. Consequently when the shaft 37 is adjusted by means of the hand wheel 58 the table .2 is raised or lowered as desired and indications on the periphery of the hand wheel are such that the operator can quickly adjust the position of the table top in accordance with the thickness of the slug being cast.

[after the matrix holder has been placed in casting position between the members of the mold, the metal pot 3 is moved forward into position to cause its mouth 43 to properly contact with the rear face of the mold preparatory to forcing the molten metal from the pot into the mold. Mounted upon the pot and projecting forward beyond or in front of the mouth of the mold is an adjustable shiftable metal core 44 which carried by the pot itself upon side bars 4 mounted upon pins 46 rigid with the pot. The bars are provided with horizontal slots 4'7 within whichare mounted comprcs sion springs 47 bearing upon the pins 46 and so arranged that the core 44 is pressed forward by spring pressure. The core 44 (omprises 2 side plates 49 which are relatively rigid and fiat and extending at an angle to each other, as best shown in Fig. 9. Their forward or inner encs are con nected by means of a flexible metal hinge connection 50 so that these platescan move from and toward each other. They are normally held separated by means of springs 51 which bear at their ends upon the two plates 49. This core is adapted to be forced into the V-notches 20 in the inner ends of the blocks 18, as best shown in Figs. 4 and 7. and are adapted to adjust themselves in contact with the inner faces of said V- notches and are held in tight contact therewith by means of the compression springs 51. The core 44 is forced forward with the pot 3 by means of an anti-friction roller 52, which contacts with a "suitable cam 53 carried by the shaft 26. The pot is held rearwardly against the action of the cam by means of a tension-spring 54. As the pot moves forward the core 44 is positioned within the V-notches in the projections 18. The pot is provided with a discharge slot 55 extending from the bottom of the pot to the mouth 43, and the positions of the mold and the core, when arrai'iged for cast ing a slug, are such that the delivery openings in the mouth of the slot are positioned immediately beneath the lower plate 49 of the core 44 and in position to deliver the metal into the slug space immediately above the lower plate 24 of the mold. The space between the upper plate 49 of the core and the upper plate 23 of the mold is closed by the forward end of the pot when in casting position.

As explained hercinbefore, it is not desirable or practicable to core very thin. slugs, and for the purpdse of casting such the core to be shifted to such a position not to interfere with the casting thereof, I provide cam surfaces 55 on the vertical side bars 5 adapted to engage the ends of the core the same is pushed forward and raise the core into a position above the mouth of the pot as best shown in Fig. 8, permitting the pot to be freely closed upon the mold as shown in said figure. The mounting of the core upon the pot by means of the rims 46 and slots 47 permits this raising of the core as described, the core being yieldingly held in its lower position by means of tension springs 56 connected to the sides of the pot and to the rear ends of said bars 45.

The metal pot is provided with a delivery piston 57 which works up and down in a cylinder 58 and forces the molten metal out through the delivery duct to and through the mouth 43. The cylinder is provided with an entrance port 59 somewhat above the connection of the duct 55 with the cylinder, which entrance port is adapted to be closed by the piston before it reaches the lower limit of its movement. The piston 57 is connected by a link 60 with one end of a lever 61, which is pivoted to the frame at 62 and is provided, between its ends, with an anti-friction roller 63, which contacts with the cam 64. The cam 64 is adapted to lift the lever and the piston, and I provide a tension spring 65 to draw the lever and piston down and discharge the metal.

If anything prevents the complete discharge of the metal from beneath the piston, the spring 65 yields and does not force the lever 61 to the lower limit of its movement.

For trimming the rear surface, or, in other words, the bottom of the slug, I provide a horizontal knife 66, see Fig, 22, extending across the machine at the rear of the mold and contacting with the rear face thereof. It is pivotally mounted on the forward ends of levers 67, which are pivotally mounted between their ends on the frame, and their rear ends are adapted to contact with cams 88 mounted on the shaft 26. The knife is held againstthe mold by guards 69 rigid with. said standards 5. The pivotal connections of the knife with the levers 67 are pin and slot connections and the knife is held tightly against the rear face of the mold by compre sion. springs 70 mounted in the slots 70 in said levers.

The arrangement of the operating cams is such that hnmediately the pot 3 is withdrawi'i sufliciently to withdraw the core out of the path of the knife 66, the knife is forced upwardly before the mold cap is lifted and while the cast slug is tightly bound or held in the mold.

The bar 9, as has been explained, is drawn forward by the springs 25 to properly posi tion the matrix holder for casting a slug, and I provide buffer springs 25 in the rear ends of the dove-tail grooves by means of which the bar 9 is guided, for the purpose of L'tif-illlODlDQ," the contacting of the matrix holder and bar 9 with the mold parts.

After the slug is cast and the mold cap is lifted sufficiently to free it from the slug, by means of the levers 97, the holder is forced outwardly and the bar 9 is returned to its original position so that the latch springs 21 can again engage it and hold it until they are released to permit another cycle or cast. The holder is forced away from the mold by means of hanging levers Tl pivoted to the inner faces respectively of the standards 5 at their upper ends and held in vertical position against said standards by means of springs 72 and adapted to be swung); outwardly by the forward ends of the levers 27.

Upon the forward ends of. each of the levers 27 I pivotally mount a sw nging block or latch 73 provided with an inwardly extending projection 74, which projections are adapted to engage the rear edges of the levers 71 and swing said levers forward as shown by dotted line '75, which indicates the path of the extreme point of one of said projections 74. As the levers 27 reach the upper limits of their movement, the rear ends of said blocks '74 contact with fixed pins 7? carried by standards 5, and cause the blocks 7 -1- to be rotated on their pivots so that the projections 74 are swung upwardly out of contact with levers 71, thus permittinr: said levers to fall back to normal position. As said levers 27' descend the blocks 73 are free to slide down the levers Tl without forcing them outwardly. When the levers 27 reach the lower limits of their movement, the blocks 73 are free of the ici'crs T1 and are free to be turned by gravity back to their positions wherein they are ready to engage the levers 71 as the levers 27 are again forced upwardly. The lower ends of the swinging levers 71 contact with the ends of the bar 9 and push it rearwardly when the levers are swung out. To cause the holder to be drawn back with the bar 9 I provide springs 9, one at each end of the bar 9 and adapted to yieldingly engage the outer ends of the holder see Fig. 1.

As best shown in Fig. 11, I provide means for releasing the holder from the bar 9 and turning it after it has been forced away from the mold so that the cast slug will depend therefrom. To effect this I provide rigid members 78 secured to the table 2 in the path of said bar 9 and rising above said bar. The upper ends 79 of said members 78 project forward over bar 9 and are ar ranged to engage the holder as it is forced away from the mold and tip it. over to the position shown in Fig. 11. The table 2 is cut away between the guides 10 .to permit the slug .to thus depend. The holder is long enough to span the opening in which the slug hangs at this time. The slug, though free of the mold, is still held in the holder by and between the endblocks 18. I

I provide a simple means for withdrawing the slug from the holder. This means consists of a pair of bars 81, one at each side of the frame, adapted to be forced forward by cams 82 mounted on the shaft 26 and held rearwardly by springs 83. The rear ends of these bars slide in guides carried by standards 84; rising from the frame and the forward ends are guided by flattened trunnic-ns 85 (see Fig. 13), which are rigid with a cross bar 86 connecting the forward ends of the two sliding bars 81. These trunnions 85 slide back and forth in horizontal slots 87 in the frame of the machine, and the fiattened trunnions 85 serve to hold the bar 86 normal with its forward edge 88 in raised position, as shown in Fig. 11. This forward edge is serrated and thin and is adapted to bite into the rear face of the slug. At the forward end of the slots 87, I make the lower wall thereof yielding, as by the flat spring 88 which permits the bar 86 to rotate upon its trunnions 85 and depress the forward edge, as shown in dotted lines in Fig. 11. To.

caus the bar 86 to turn as described, I provide a cam projection 89 on the rear lower edge of the bar adapted to engage a fixed pin 90, rigid with the frame of the machine, as the bar 86 is moved forward and just as it reaches the forward limit of its movement. As soon as the bar begins to recede from the forward position the springs 88, by acting upon the flattened trunnions 85, cause the bar 86 to turn back to its normal position as the projection 89 leaves the fixed pin 90, then the trunnion is in position to enter the horizontal slot 87 whereby the forward edge 88 is retained in raised position ready for contact with the next slug.

Opposed to the bar 86 I provide a companion bar 91 pivotally mounted on trunnions 92movable in horizontal slots93 so the bar 91 can move forward and back. Bar 91 is normally held toward the opposite bar 86 by springs 94 mounted in said slots 93 and bearing upon the trunnions 92. I provide springs 95 to normally hold bar 91 in an upwardly inclined position, as shown in full lines in Fig. 11, and against the stop 91'. The rear edge 96 of the bar 91 is serrated and thin like the slug engaging edge of the bar 86 and is adapted to engage the slug for the purpose of assisting in withdrawing the slug from the matrix holder. This thin edge 96 is normally opposed to the edge 88 in its raised position and these two edges are adapted to receive the slug between them as the holder is turned over as hereinbefore described. The forward movement of the bar 86 serves to cause the slug to be engaged by these two serrated edges and the tipping action of the bar 86, by reason of the two bars engaging the slug, causes the opposed bar 91 to follow down coincident with the downward movement of the bar 86, and thus draw or pull the slug out of the holder.

is the line of matrices in the holder may be of different lengths as explained hcreinbefore, the movable projection 18 may occupy various positions in the length of the holder, and to permit the thin edges of the extractor bars 86 and 91 to bite into the slug, I provide grooves or slots 97 in the outer surfaces in said projections 18 to clear the serrated edges of said bars. These slots or grooves 97 are spread cr ually with the points oi"? said serrated edges and the spaces are made deft nite in accordance with certain practices among printers of having the thickness of letters or matrices vary by certain definite amounts, such as one point or one-half point.

In order to release the latch spring 21 to permit the bar 9 to be drawn forward and to start or release the machine, I provide a starting lever 98 mounted upon the outer end of a horizontal shaft 99, which extends across the machine below the table 2. Normally the lever 98 stands up in convenient position to be grasped by an operator standing in front of the ma hine. Upon the shaft 99, I provide upwardly extending levers 100 having transversely extending upper ends 101 which extend over and are adapted to depress the latch springs 21 to release the be r 9 when the starting lever 98 is moved in the direction of the arrow on Fig. 2 to start the machine into operation.

To permit the vertical adjustment of the table 2 without interfering with the action of the levers 100 and projections 101, I provide the spring latches 21 with deep recesses 21 below the normal positions of the pro je tions 101, the relatively highest positions of the projections 101 being always below the top surface of the table 2 and out of the path of the bar 9.

I provide an electric motor 102 to furnish power to operate the machine, and I provide a clutch pulley 103 on the shaft 26 for transmitting power to the machine. I control the clutch pulley by means of the lever 98 through the medium of a bell-crank 10 1, one arm in operative relation to the clutch pul ley and the other connected to the lever 98 by the link 105.

The clutch is of a well known type which will cause one revolution of the shaft 26 upon putting the clutch into action and will be automatically released and the shaft 26 stopped at the end of the one revolution; consequently when the lever is drawn for ward to start the machine it is immediately released and the shaft 26 makes but one revolution.

To receive the slugs as they are with drawn from the matrix holder, I provide a curved slide 106 having a stop 107 at its forward edge and arranged to slide the slugs to the forward part of the machine Where they can be readily removed for as sembling in proper relation to make up a type form. The shavings made by the knife 66 drop down back of the guard 106 and hence do not become mixed with the slugs.

The upper and lower parts of the mold are long enough to make a slug the full length of the holder, that is, to make a sing the full length of the extreme or maximum space possible between the projections 18 on the holder blocks 16 and 17. Also the mouth 43 of the pot is of a width, transversely of the machine, equal to the maximum distance between the blocks 16 and 17.

To prevent the pot from discharging iiolten metal between the block 17 and the adjacent end of the matrix holder at times when the line of matrices is shorterthan the maximum length, I provide a bar or slide 108 mounted to move transversely of the machine and into and out of the mold space. This bar is horizontal. and in alinement with the mouth 43 of the pot when the same is in casting position. The bar slides back and forth through a suitable guide opening in one of the standards It is thick enough vertically to close the adjacent part of the mouth It is wide enough to fit nicely upon the mouth of the pot and its inner end contacts with the side of the projection 18 on the block 16, movable so that when the mouth of the pot is in cast ing position and the bar 108 extends into the slug space with its inner end contacting with the block 18, metal cannot escape from the portion of the mouth thus closed.

To automatically move the bar 108 in and out I provide a swinging bell-crank 109 pivotally mounted at the extremity of its shorter arm 110 upon the upper part of one of the standards 5. The longer arm 111 extends downwardly and is adapted to engage a roller 112 carried by the outer end of the bar 108 and is adapted to force said bar 108 outwardly when the shortv arm is raised. The bar 108 is normally held in wardly by tension spring 11.8. The short arm is raised by the mold cap 8, this being provided with an adjustable stop or screw 115 for contact with the lower edge of the arm 110 to raise same as the cap 8 is raised. The arrangement is such that as the cap 8 is lowered into place, into contact with the .projectiijms 18, the bar 108 is free to be drawn inwardly by the spring 113 until its inner end contacts with the adjacent face of the block 17, and it thus automatically closes the adjacent part of the mouth 43 of the metal pot.
